Dunham will voice the role of Candace in the season 27 premiere, titled "Every Man's Dream." The episode sees Homer diagnosed with narcolepsy — but instead of returning home with his prescription medication — he returns home drunk. He and Marge visit a marriage counselor and have a trial separation, during which Homer begins dating a 20-something. Dunham will voice Homer's new squeeze.

Apatow's Simpsons episode — which was written as a spec in 1990 before the prolific producer behind Freaks and Geeks, Undeclared and several feature films — airs on Sunday at 8 p.m. on Fox. Check back later to THR's The Live Feed for an interview with Apatow and showrunner Al Jean about the episode.
